Bird damage prevention device for transformer substation isolating switch

Abstract

The invention provides a bird damage prevention device for a transformer substation isolating switch. The bird damage prevention device for the transformer substation isolating switch comprises a square shell, an ultrasonic buzzer and a mechanical assembly, wherein the ultrasonic buzzer comprises a singlechip, an ultrasonic generation device, a control circuit, a sensing piece and a storage battery; the ultrasonic generation device is connected with the singlechip through the control circuit; the control circuit is connected with the storage battery; the sensing piece is connected with the singlechip and is connected with the storage battery; the singlechip, the ultrasonic generation device, the control device and the storage battery are placed in the shell; and the sensing piece is embedded in the wall of the shell. After the device is placed in a gap of the isolating switch and fills the gap; meanwhile, the sensing piece transmits information to the singlechip after sensing that birds are close to the device, the singlechip controls the ultrasonic generation device through the control circuit to send out an ultrasonic signal, and the ultrasonic signal is amplified by a loudspeaker, so that the aim of repelling the birds is fulfilled.

Description

technical field [0001] The invention relates to an anti-bird device for an isolating switch of a substation, and belongs to the technical field of bird repellents. Background technique [0002] Substations are generally far away from urban areas and close to fields and woods. The vegetation and crops around the substation are lush, and bird activities are frequent. The isolation switches of 35kV and above in the substation are generally arranged outdoors, which is very suitable for birds to live in, and the phenomenon of bird nesting is serious. , During the inspection and cleaning of the bird's nest, it was found that there were grass, plastic strips and other sundries on the ground under the bird's nest, and the nesting materials included branches, dead vines, waste cotton thread, and even iron wire. The whereabouts of these materials may be short-circuited, if These debris falling on live equipment may cause equipment grounding, short circuit, or even equipment failure, b...

Problems solved by technology

[0002] Substations are generally far away from urban areas and close to fields and woods. The vegetation and crops around the substation are lush, and bird activities are frequent. The isolation switches of 35kV and above in the substation are generally arranged outdoors, which is very suitable for birds to live in, and the phenomenon of bird nesting is serious. , During the inspection and cleaning of the bird's nest, it was found that there were grass, plastic strips and other sundries on the ground under the bird's nest, and the nesting materials included branches, dead vines, waste cotton thread, and even iron wire. The whereabouts of these materials may be short-circuited, if These sundries fall on live equipment, which may cause equipment grounding, short circuit, or even equipment failure, bird droppings flashover, short circuit failure, etc., seriously affecting the safe operation of equipment

When operating the isolating switch, the personnel on duty found that there was an action of the electric operating mechanism, but the isolating switch refused to open and close. The reason was analyzed that there was a large gap in the support part of the isolating switch and the outer cover of the transmission rod, and a large number of birds nested. Grass, feathers, soil and other debris are caught in the middle of the transmission connecting rod, causing mechanical jamming, resulting in improper opening and closing, and causing serious harm to the safe operation of the substation

[0003] At present, it is mainly to clean up after the bird's nest is found during the inspection of the line, which is far from enough to realize the safety and reliability of the distribution line, and will cause passive operation and management of the line.
